To all whom it may omzoem:

Be. it known that I, Renner fi.- *S'ronn a citizen of the United Sta-tes,4 residing at Northboro, in the county of Worcester and Commonwealth of Massachusetts, hsve 1nvented e new and useful Improvement in Track-Sanden, oi' which the oilowing, taken in connection withl the aceompanymg' drawings, is aspeeication. 4

The "present invention'relates te epparatus carried by street oars or locomotives for the purpose of deliveringfsand upon thetraclz rails, and its object is to provide s simple, compact and elicient device of the character speciiied, by means of-whiclr the instantaneous delivery ofsa'nd upon the rails'ii swamplished whenever desired:v t Other and -further objects will, appean.

embodiment of my inventomreferelroeb'e ing had to Athe`acoompanying mwhich- Figurelis aside elevation, pt xrtly 1 1; tion, showing the ap lioatims-.ofimysmven tion ,Lo a street our.' ig'. 2 isl-g erticgllom gitudinal' section through the contano-.j ing trough or boxg andwEig'. 3 is e. section on the -line 3*-3 ofFig. 2. l

parts inthe several The numeral l indicates, sind containing box or trough, which, the'.-presentmstance, is shown disposed beneaththe seat of the oar. The boxl 1 is preferably 1`n the form of an elongated trough closed at the ends and having its side walls downwardly' converging from a point above the bottom.

a cen't'ally disposed rectangular feed opening 3, which is closed bye door 4 hinged to seid cover Beneath said opening 3 is suspended a screen 5 having its edges bent upwardly and secured by rivets to a iange of the cover. e y

iVithin the bon. l e hood or deilector 6 extends longitudinally from end to end'of the same, the said hood preferebiy being inverted v shaped in cross section and pro` jee-ting upwardly from the edgesformed by the sides and bottom of the box as shown in Figui 3, Between eachend thereof and its centnafl portion each side of the hood 6 is cut away as shown et 7,7,to permit the send,

which piles up in the longitudinally extending channels between the sides of the box i neeted afflexibletube or Vvl downwardly toftl'ie'rails on which-.the car moves.

referred to as blast chambers. The parti tion 8 is carried by and is preferably integral with 'a conduit 9 supported by an annulai base flange 10 restino; on the bottomof the boxl and communicating with' both, of seid blast chembers by means of an open upwardly extending' section 1l-Which is dihmetrically divided by said partition 8. To the 'lower end of the conduit 9 is con-Y pipe 12, which is?" so as to have its open lower end disposedso-'as to deliver sand upon one A pipe compressed air or any passes 'through anflfls-supportedby. said rtii'on 8, the said. pipe; extending thi'ofug:l both.-'of said blast ohombeis vfor vsobstantelly .the entire length ofthe ksame; The'1end.of `pipe 13 in ones-'ofssaid chambers, in the present 135,y dapted toconvey instance themight hand-lor forward blast Like' reference characters-indiane like` chamber, `hasmoulinet/edf,thereto vone horizontalai'inpf aT- co'ipling 14, the dependingt vertical arm' ofV which is closed at the 'bottom andhasa-plurality of lateral 'openings-J5 onthe side facing the partition 8. 'The'other horizontal arm of the V14 isattached to a compressed .pipe 'lvwhich passes through theend Wall g the bbx and acts as a support for the end A removablencoyer 2 is adapted to dt snugly Oi over the bonsaid cover being providedwith 'if-coupling aix-"supply pipe 13. The other has connected thereto anelbow coupling 17 closed at the hotf-v tom, and provided with e series of lateral openings 18 in. opposition-v to the open.- ings 15 in coupling 14. The supply pipe 16 has a valve 19, at afp'oint conveniently accessible for operation by the motorman of the' oer, by 'means of which he'may ,cause a blast of compressed air, supplied VAfrom the usuel tank, not shown, 13 et such times es may be desired.

The operation of my improved device is as follows The box issupplied withv sand through the opening` 3, the? sandr4 sifting through the screen 5 and dropping by gravity onto thehood 6, and piiing up to enter the pipe in the longitu- 1 lo dinal channels formed between the sides of height Kto l'thronn'h the l,ori-"f tions 7; these cut away portionsrjare spaced. from the ends ofthe hood so as to prevent f the piling up .of sand around the- Vcouplings le and l7,.and, furthermore, they terminates.

short of the space occupied by the section l1 of the conduit 9, so that sand within the j said blast chambers will have no` tendency be` sanded,-

to pass into said conduit unless forced into the same by a blast of air. When the operator opens valve- 19, a series of blasts .of compressed air are made eiective from the outer end of each blast chamber to force sand lying Within such chambers over the edge `ofthe Asection 11, against the partition' 8 vandthrough the conduit 9 to the rail to The construction of thev hood ac'ilitates'the above described movement of thefsand since the sand is prevented from box, a blast chamber'v Within said sand containmgboxv in communication therewith intermediate its ends, and means for direct- Hin' *a blast-of air longitudinally ot' said blst chamber.
